How to wash a mattress from bedbugs? - briefly
Remove the mattress cover, apply a high‑temperature steam cleaner or an EPA‑approved bed‑bug spray, then vacuum thoroughly and expose the mattress to direct sunlight or a dryer on high heat for several hours. This combination kills all life stages and eliminates residual eggs.
How to wash a mattress from bedbugs? - in detail
Cleaning a mattress that harbors bed‑bugs requires a systematic approach to eradicate all life stages and prevent re‑infestation.
Begin by confirming the presence of insects. Look for live bugs, shed skins, tiny dark spots (feces), and bites on the skin. Isolate the bed by removing all linens, pillows, and accessories. Wash these items in hot water (≥60 °C) for at least 30 minutes, then tumble‑dry on high heat for a minimum of 20 minutes.
Next, vacuum the mattress surface and seams thoroughly using a hose attachment. Empty the canister into a sealed bag and discard it outside the home. Follow vacuuming with a steam treatment: a commercial steamer delivering steam at 100 °C for 10‑15 seconds per spot penetrates fabric and kills eggs and nymphs. Move the nozzle slowly to avoid overheating the material.
Apply a residual insecticide approved for indoor use on fabrics. Spray evenly across the entire mattress, focusing on seams, folds, and tufts. Allow the product to dry according to the label instructions, typically 4‑6 hours, before re‑assembling the bed.
Encasement is essential for long‑term protection. Place a zippered, bed‑bug‑proof cover over the mattress and box spring, sealing it tightly. Keep the cover in place for at least 12 months; any bugs trapped inside will die without a blood meal.
If the mattress cannot tolerate steam or chemicals, consider heat‑based eradication. Place the mattress in a sealed chamber or a large dryer capable of maintaining 55 °C for 90 minutes. Alternatively, transport the mattress to a professional service that uses cryogenic (‑30 °C) treatment.
After treatment, monitor for signs of activity for several weeks. Use interceptors under each leg of the bed to capture wandering insects. Repeat vacuuming and steaming if any evidence of resurgence appears.
Finally, maintain a preventive routine: keep clutter away from the bed, inspect second‑hand furniture before introduction, and perform regular laundering of bedding at high temperatures. Consistent vigilance reduces the likelihood of future infestations.
